How much does a taxi cost from taoyuan international airport to Yilian?

The distance between these two places is not that close. So the cab fare will be very expensive. So it's suggested to change another way to go Yilan.
Upon landing, take airport shuttle bus to get to Taoyuan Railway Station first. It costs NT$45 per person. Then take the train to the destination. The schedules are 06:50, 08:50, 09:19, 09:31, 15:19, 17:19, 18:32, 20:15 and 20:50. And the ticket fare is NT$200 to 270 per adult.
